• Ignition on.

  Read off which switch was activated when the diagnostic trouble code (DTC) was set by clicking on the VCT2000 symbol in VIDA (Volvo-specific scan tool).

  Check if the switch is sticking due to dirt or there is an obstruction preventing the switch from returning.

  Check that the functions that can be controlled via the switch on the climate control module (CCM) are working.

  Also check that the LEDs in the switches light and go out when the buttons are pressed.

  The keypad must be replaced if the switch does not spring back and the fault is not due to dirt or an external object.
